I am looking for a device for subliminal mind control.
I've found ultrasonic tracks on Amazon. Also I'm aware of ultrasonic sound generators that can be modulated by software (similar to Software Defined Radio). But I'm searching for the device that can be just connected to smartphone and play ultrasonic track out-of-the-box and powered by batteries.
Desired Technical Characteristics
Frequency: 40-100 KHz
Output: 25-100 W
Input: 12-36 V DC
Price
$300-500
